Sometimes the easiest path is also the most successful.
Small-scale growers that propagate infrequently can skip a lot of the worry that accompanies the rooting process.
Aeroponic cloning machines, humidity domes, and all the other "accouterment" can be replaced with a simple cup of water.
Although not a viable strategy for commercial growers, this home remedy for rooting cuttings has a surprisingly high success rate.
The key is to keep the water oxygenated by replacing it once or twice a day. Stagnant water is depleted of oxygen, and as a result, stems sitting in stagnant water may begin to rot before the roots have a chance to form.
Keep light and temp levels in check, change the water frequently, and watch what happens!
